Abstract (en)
[origin: EP0219826A2] A complete integrated circuit processing module, wherein multiple processing stations 104, each with its own vacuum isolation, are located inside a single module 102 which is held at hard vacuum. A wafer transport arm mechanism 106 permits interchange of wafers among the processing stations 104 and a load lock 12. The load lock 12 is equipped to remove and replace wafers from a vacuum-sealed wafer carrier 10. The wafers remain face-down and under hard vacuum during all the wafer handling steps.
[origin: EP0219826A2] The load lock comprises a chamber having a vacuum-sealable lid and a space within the chamber where a wafer corner containing wafers of a predetermined diameter can be placed. An elevatable and extensible transfer arm contains support elements so that one of the wafers of the predetermined diameter can be supported by the transfer arms with edge contact only. The transfer arm comprises along it periphery a number of pins having conically tapered upper portions and is spaced to support the wafers. An operable vacuum-tight port in the side of the load lock is positioned so that the transfer arm can be extended through the operable port while carrying a wafer.
